Painting on Metal Surfaces

The process of on Metal Surfaces can be divided into three steps:

  • Pre- work
  • Surface preparation
  • Painting

Pre-painting Work

Surface should be free from dirt, dust, grease, rust, moisture etc. The area which is not to be painted must be covered by a masking tape, paper and/or cloth.

Surface Preparation

  • De-grease and de-rust ferrous metal substrates by suitable treatment.
  • For nonferrous metal substrates like aluminium as well as galvanised iron, tin, etc, pre-treat the surface with Apconyl Wash Primer – WP 636. For ferrous metal substrates, apply Metal Primer – Corrosion Resistant either by brushing or spraying.
  • If necessary, the use of Knifing Paste Filler is recommended to fill up dents and rectify surface imperfections.
  • Ensure that the surface is free from moisture and loose matter.
  • Apply one more coat of Metal Primer- Corrosion Resistant by brushing or spraying to cover puttied areas.
  • For best results, allow the primer coat to dry for 6 hours and dry sand with emery paper no. 320 before application of subsequent coat.

Painting

For best results
Allow the surface to dry overnight after application of primer as above.
Apply top coat using the recommended thinner. For best results, apply two coats allowing 8 hours of drying time between two coats.
The first coat should be wet sanded with waterproof emery paper grade 400 before applying the second coat.
